The first statement may be referring to the Cramer-Rao bound: https://en.wikipedia.org/wiki/Cram%C3%A9r%E2%80%93Rao_bound But it only applies to estimation (like how well a populat…

Just speaking in terms of "quantum size" (and not computing power, which is not understood yet), it depends on the graph of possible entanglements among the qubits. If it were a co…

It wasn't really shown to be faster; see http://www.scottaaronson.com/blog/?p=1400 . To focus on the "3600 times" issue, I suggest searching for the strings " Ising" and "CPLEX". D…

It's not able to do full quantum annealing; it's only able to use stoquastic Hamiltonians on a fixed topology. Even if truly quantum effects were present (which is unclear at the m…

To clarify, there are public-key cryptosystems with no known quantum attacks, but it's not known how to build such systems based on problems that are known to be QMA-complete (or N…

Try piping into psub, as in paste (hquery -q '//a/@href' x | psub) (hquery -q '//a' x | psub) http://ridiculousfish.com/shell/user_doc/html/commands.html#...

What have I said that suggests "MIT is not to blame for very much at all"? My comments have dealt with factual issues; I don't see where I advanced any opinions on MIT's deserved l…

If by "objected to FOIA requests" you mean "filed a motion, just like JSTOR, proposing the ability review and suggest redactions to the requested documents over a window of five da…

From http://swartz-report.mit.edu/docs/report-to-the-president.pd... , Appendix 14, Question 35: > 35. What influence, if any, did MIT exercise or could it have exercised in the pl…

> The report appears to find that MIT should not have changed its neutral stance, which is disappointing, and I'm skeptical. The report does not have any findings about what MIT "s…

The USC group has a response to Smolin and Smith which explains how some quantitative features are still best explained by a simulated quantum annealer: http://arxiv.org/abs/1305.5…

That computation is probably something you were already familiar with in disguise: it's just the law of cosines [1][2] along with the fact that a matrix of inner products can be co…

I just ran Wes's benchmarks (not the BLAS call versions) on my machine with a Julia I built on 10/13 (17c3c13), and the timings have indeed improved. For the details, see this gist…

They actually point out a specific comparison to FFTW in the paper: their "preliminary implementation" is faster than FFTW for n=2^22 and k I don't know how to estimate what values…

Lee Smolin argues pretty concretely and convincingly that the anthropic principle cannot be science because it cannot yield falsifiable predictions: http://arxiv.org/abs/hep-th/040…

It was debunked by some of the top minds in the world (e.g. Terry Tao), though the author's webpage states that it's under journal review. Here's the "official" debunking summary o…

For the record, the iPad is $499/$599 for 16/32 GB (WiFi) models, not $599/$699 as you stated: www.apple.com/ipad http://store.apple.com/us/browse/home/shop_ipad/family/ipad?...

Those are a lot of great links! But I disagree with your "BTW" line: I don't think factor graphs are more popular than Bayes nets (a.k.a. directed graphical models), at least not i…

Just so you know, the Latent Dirichlet Allocation is very much a Bayesian model, as it says in the original paper's abstract [1] (first google hit). (LDA is a bit of an overloaded …
